8y + 12 - y = 61
8y - y + 12 = 61
7y + 12 = 61
7y = 61 - 12
7y = 49
7y/7 = 49/7
y = 7

Randi has a party-sized sandwich that is 3/4 yard long. She will cut it into smaller sandwiches that are each 1/12 yard long. Wh

Elena L [17]

Answer:

The expression for number of sandwiches is $n=\frac{3}{4}\div\frac{1}{12}$

9 small sandwiches can be made.

Step-by-step explanation:

Given:

Length of party-sized sandwich (l) = 3/4 yard

Length of each small sandwich (s) = 1/12 yard

Now, let the total number of small sandwiches be 'n'.

Now, sum of all the lengths of small sandwiches will be equal to the length of the party-sized sandwiches.

Therefore, framing in equation form, we have:

Length of large sandwich = Length of small sandwich × Total number of small sandwiches.

$l=s\times n\\\\n=\dfrac{l}{s}$

Now, plug in the given values and solve for 'n'. This gives,

$n=\frac{3}{4}\div \frac{1}{12}\\\\n=\frac{3}{4}\times \frac{12}{1}\\\\n=\frac{36}{4}=9$

Therefore, 9 small sandwiches can be made.

In the diagram below line m is parallel to line n

Dovator [93]

You need to find the angle measurements of the triangle.
The angle supplementary to 128 measures (180 - 128 =) 52 degrees.

Using the corresponding and supplementary property because lines m and n are parallel, you know that the highest (in location) angle of the triangle measure 90 degrees.

A triangle's total angle measurements add up to 180 degrees. Subtract the other two known angles from 180. 180 - 52 - 90 = 38. The third (right side) angle of the triangle measures 38 degrees.

Now, using the supplementary angle theorem, you can find angle a, which is supplementary to the third angle on the triangle. 180 - 38 = 142.

Angle a measures 142 degrees.
